What Does Bt Mean in Crops

Bacillus thuringiensis (Bt) microbial pesticides have a 50-year history of safety in agriculture. Cry proteins are among the active insecticidal ingredients in these pesticides, and genes coding for Cry proteins have been introduced into agricultural crops using modern biotechnology.

What is Bt gene?

Bacillus thuringiensis, or Bt, is a common soil bacterium whose genome contains genes for several proteins toxic to insects. … The resulting mature plant has the Bt gene in all its cells and expresses the insecticidal protein in its leaves. Caterpillars ingest the toxin, which fatally damages the lining of the gut.

What does Bt stand for and its importance?

Bacillus thuringiensis is a gram-positive, spore-forming bacteria which is mainly found in the soil. As stated above, it produces proteins that are toxic to insects. Organic farmers use this bacterium in a solution and spray it on the plants to protect them from pests.
